abstract：:Hepatitis C virus (HCV) encodes a polyprotein that is processed to produce the structural and nonstructural proteins of the virus. Nonstructural protein 3 (NS3) is a serine proteinase that cleaves the polyprotein to release the NS4A, NS4B, NS5A, and NS5B proteins. To characterize the substrate specificity of NS3, we s...
